Title: Internal-combustion engine
Inventor: SAKAI TAKATOSHI
IPC: F01L13/08
Filed: 1983-10-07
Abstract: PURPOSE:To obtain a large effect of decompression so as to easily start an engine, by opening an intake or exhaust valve to its large opening in the rising stroke of a piston and closing the valve when the piston approaches its top dead center, when the engine is started. CONSTITUTION:When an engine is normally driven, an exhaust valve 3 is opened and closed by a rocker arm 5 swivellably moved by a cam 4. A cam 8 for decompression is adapted to the rocker arm 5, and the valve 3 widely opens in the rising stroke of a piston 6, both relieving the compression and accumulating energy in a flywheel. The valve 3 is closed when the piston 6 approaches to its top dead center. The engine, if a speed of its crankshaft increases, is transferred to its normal operation by releasing adaptation of the cam 8 to the rocker arm 5 through a driving means 12. In this way, a large effect of decompression is obtained because the valve 3 is widely opened at the time of decompression.
